Landing Summary

The Boeing 777-200ER touched down on runway 04R at KBOS Logan International Airport with a good threshold height, allowing the crew to maintain a stable approach profile. The final approach was initiated from the south, heading 20.0° at 4 nm and 1,267 ft above ground level. The aircraft's speed was well-managed, with a threshold speed of 138 kt, which was within the acceptable range. The touchdown distance of 426 m was also satisfactory, indicating a smooth and controlled descent.

Upon touchdown, the aircraft's speed was 135 kt, which was within the recommended range for a firm touchdown. The touchdown rate of -301 fpm was firm, but not excessively hard, suggesting that the crew had maintained good control of the aircraft's descent. However, the runway touchdown position was slightly misaligned by 5.9 m from the centreline, which may have been due to a slight deviation in the approach path. The local weather conditions, with a temperature of 7 °C and winds of 8 kt at 140°, were not particularly challenging.

The total landing distance of 1,357 m was 58% of the runway length, which was within the acceptable range. The runway rollout alignment was also slightly misaligned by 7.8 m from the centreline, which may have been due to a slight deviation in the aircraft's direction during the rollout phase. Despite these minor deviations, the overall landing performance was satisfactory, with a score of 96.8%. The crew's ability to maintain a stable approach profile and control the aircraft's descent was commendable, and the landing was completed safely and efficiently.
